Abstract
The utility model discloses a powder materials screw conveyer of material is rush out to acrotism, including going into hopper, pipe wall and lumen, the pipe wall is lieing in the part that wall thickness degree between pan feeding section L1 and the pay -off section L3 diminishes gradually does changeover portion L2, lumen 2 is in changeover portion L2's internal diameter is the grow gradually. The utility model discloses can reduce filling coefficient effectively, make powder materials when the pay -off section is carried, powder materials is located the latter half of pay -off section lumen internal diameter all the time, has avoided the emergence of the pulse ejection of compact condition.
Description
Technical field
The utility model relates to technical field of conveying machinery, particularly relates to a kind of powder material conveyor screw of no pulse discharging.
Background technology
Conveyor screw is conventional continuous conveyor.Work as manufacturing enterprise, especially the enterprise of powdery paints is produced, when using circular tube spiral conveyer conveying conventional in prior art to have the body of powder of high flow, this high flow and screw conveyer structure bring the problem such as discountinuity, pulsation and non-quantitation of powder conveying, the series of problems such as cause downstream mixing equipment or the fluctuation of Fabricating machinery negative pressure is large, material is excessive.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of powder material conveyor screw of no pulse discharging.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of powder material conveyor screw of no pulse discharging, it is characterized in that including hopper and conveyor screw; Described conveyor screw comprises tube wall and tube chamber; In described tube chamber, screw rod is installed, described screw rod is provided with pivoting leaf;
Described tube wall is divided into pan feeding section L1, transition phase L2 and feeding section L3 successively according to throughput direction; Described pan feeding section L1 is positioned at the below of described material bin; The lumen diameter H1 of described pan feeding section L1 is less than the lumen diameter H2 of described feeding section L3; Described tube wall is described transition phase L2 in the part that the thickness of pipe between described pan feeding section L1 and feeding section L3 diminishes gradually, and described tube chamber 2 becomes large gradually at the internal diameter of described transition phase L2.
Through measuring and calculating, the ratio of the lumen diameter H1 of described pan feeding section L1 and the lumen diameter H2 of described feeding section L3 is 1:1.3 ~ 1.5.
Principle of work of the present utility model and beneficial effect are: the pan feeding section lumen diameter of conveyor screw is less than the lumen diameter of feeding section, effectively can reduce fullness coefficient, make powder material when feeding section is carried, powder material is positioned at the latter half of feeding section lumen diameter all the time; The helical-blade of screw rod end can have the larger material of enough space stop capacity when discharging, avoid the generation of pulse discharging situation.
Accompanying drawing explanation
Figure 1 shows that a kind of structural representation of powder material conveyor screw of no pulse discharging.
Figure 2 shows that tube wall segmental structure schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Be illustrated in figure 1 a kind of powder material conveyor screw of no pulse discharging, include hopper and conveyor screw; Described conveyor screw comprises tube wall 1 and tube chamber 2; In described tube chamber 2, screw rod 3 is installed, described screw rod 3 is provided with pivoting leaf.
As shown in Figure 2, described tube wall 1 is divided into pan feeding section L1, transition phase L2 and feeding section L3 successively according to throughput direction; Described pan feeding section L1 is positioned at the below of described material bin; The lumen diameter H1 of described pan feeding section L1 is less than the lumen diameter H2 of described feeding section L3; Described tube wall 1 is described transition phase L2 in the part that the thickness of pipe between described pan feeding section L1 and feeding section L3 diminishes gradually, and described tube chamber 2 becomes large gradually at the internal diameter of described transition phase L2, and described transition phase L2 is gradient structure 6.This design of the present utility model can reduce the fullness coefficient of powdery paints effectively, and make powder material when feeding section is carried, powder material is positioned at the latter half of feeding section lumen diameter all the time; The helical-blade of screw rod end can have the larger material of enough space stop capacity when discharging, avoid the generation of pulse discharging situation.
Through measuring and calculating, the ratio of the lumen diameter H1 of described pan feeding section L1 and the lumen diameter H2 of described feeding section L3 is 1:1.3 ~ 1.5.
Accordingly, due to the difference of lumen diameter, described helical-blade is pan feeding helical-blade 4 in the part of described pan feeding section L1, and described helical-blade is feeding screw leaf 5 in the part of described feeding section L3; The spiral external diameter of pan feeding helical-blade 4 and feeding screw leaf 5 is than being 1:1.3 ~ 1.5.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
